2 Technical Specifications

2.1 Product DescriptionAspirating smoke detectors from the FAS-420 series are active fire detection devices that are connected directly to the Local SecurityNetwork (LSN) "improved version" for early fire detection. They are used for room and equipment protection as well as for monitoring air-conditioning units or ducts.Local SecurityNetwork (LSN) improvedThe FAS-420 series aspirating smoke detectors were developed specifically for connection to the FPA-5000 Modular Fire Panel and offers the upgraded features of the LSN "improved version" technology.– Flexible network structures, including T-tapping with no additional elements – Up to 254 LSN-improved elements per loop or stub line – Unshielded cable can be used. The FAS-420 series also offers all the established benefits of LSN technology. The operating data and fault messages can be read off the FPA-5000 operating and display unit.VariantsThe FAS-420-TP1, FAS-420-TP2, FAS-420-TP1-SL and FAS-420-TP2-SL variants feature LED displays indicating operating mode, faults and alarms (the FAS-420-TP2 and FAS-420-TP2-SL have two alarm displays). The FAS-420-TT1, FAS-420-TT2, FAS-420-TT1-SL and FAS-420-TT2-SL offer differentiated alarm displays (info, pre and main alarm) as well as a 10-segment smoke level display (on the FAS-420-TT2 and FAS-420-TT2-SL, all alarm and smoke level displays are doubled).The FAS-420-TP1, FAS-420-TP1-SL, FAS-420-TT1 and FAS-420-TT1-SL variants are each fitted with a detector module. The FAS-420-TP2, FAS-420-TP2-SL, FAS-420-TT2 and FAS-420-TT2-SL variants each have two integrated detector modules. Two aspiration pipes can be connected, enabling two areas to be monitored. This effectively doubles the monitoring area.Dual-detector dependencyThe use of two detector modules in variants FAS-420-TP2 and FAS-420-TT2 also enables a dual-detector dependency to be realized. This means that one area can be monitored by two pipe systems.Two alarm stagesAlternatively, the FAS-420-TP2 and FAS-420-TT2 can have two alarm stages configured. A pipe system is connected via a pipe adapter on two detector modules. Selecting different response sensitivities for the detector modules enables the time-staggered triggering of two main alarms.Dual-zone dependencyConnecting to the FPA-5000 Modular Fire Panel and programming using RPS software also permit a dual-zone dependency.SensitivityThree detector module versions are available for the FAS-420 aspirating smoke detector series:– DM-TT-50(80) with a response sensitivity of up to 0.5%/m (0.8%/m) light obscuration– DM-TT-10(25) with a response sensitivity of up to 0.1%/m (0.25%/m) light obscuration– DM-TT-01(05) with a response sensitivity of up to 0.015%/m (0.05%/m) light obscuration Depending on the detector module used, the FAS-420-TT1 and FAS-420-TT2 models can achieve a resolution ten times higher for displaying up to 0.05%/m (0.08%/m), 0.01%/m (0.025%/m) or 0.0015%/m (0.005%/m) light obscuration. Further sensitivity levels to suit the


Technical Specifications | en 9


application range can be selected via the RPS programming software.

The new High-Power-Light-Source technology permits a broad detection spectrum over all standardized fires (for response sensitivity, detection points, see Section 3.4 Defining the Response Sensitivity, page 37).LOGIC · SENSThe intelligent signal processing LOGIC · SENS distinguishes between deception variables and fire events in order to prevent false alarms.Reliable airflow monitoringAnalogous to point-type smoke detectors, which are monitored electronically for wire breaks and short-circuits, highly sensitive and dependable airflow monitoring is required for smoke aspiration systems. The airflow sensors used in the FAS-420 series reliably detect malfunctions such as pipe breakage or obstructions in the air sampling openings.The small airflow unit also contains a dynamic airflow sensor that enables a response to small and fast changes in the airflow.Airflow monitoring is temperature-compensated and can be set depending on the air pressure.Patented air sampling openingsThe air sampling openings of the pipe system require clearly defined bore diameters that depend on the planning and design. These precise air sampling openings are created using patented aspiration reducing film sheets, marking tape, and clips, which not only permit easy installation, but also prevent "whistling" noises. Another advantage is the quick and easy detection and checking of the air sampling opening diameters.Point-type detector projectionThe system’s aspiration points can be equated with point-type smoke detectors. The monitoring areas can therefore be planned in accordance with the applicable national regulations.DiagnosticsA system with FAS-ASD-DIAG Diagnostic Software, which enables quick and convenient error containment, is available for maintenance and service. The current and stored unit status is read-out via cable data transmission to the PC.Selecting the fan voltageThe fan voltage for special planning can be increased from 6.9 V to 9 V by relocating the fan jumper. This increases the air transport speed and therefore reduces detection time. For -SL variants, the fan voltage can also be set to 6.5 V.

NOTICE! The sensitivity value is based on measurements with standard test fires (old value in brackets).



2.2 Areas of ApplicationThanks to their detection principle, FAS-420 aspirating smoke detectors represent an extremely versatile fire alarm system. PrincipleAir samples are taken from the monitoring area by a pipe system with defined aspiration openings and then fed to the detector module. This is especially well-suited for areas in which point-type detectors cannot be used or can only be used under certain circumstances. These include:– Areas that are difficult to access, in which point detectors are difficult to install and

maintain– Air-conditioned areas– Areas with a height greater than that allowed for point detectors– Areas in which point detectors are not desired for aesthetic reasons– Areas in which electromagnetic fields are influential– Areas that are exposed to high or low temperatures– Areas with contaminated air that require filter elements– Areas that must be protected against vandalism.Space protectionThe FAS-420 series is suitable for monitoring areas such as– Those with double floors, false ceilings– Tunnels, ducts, barely accessible hollow spaces– Storage, high-rise warehouses, elevator shafts– Museums, cultural institutions– Freezer storage.

Area monitoring with air-conditioningArea monitoring occurs– In rooms with air-conditioning for server rooms etc.– In ventilation ducts– Over double floors, false ceilings– In IT rooms, e-distributor rooms, transformer cells– On air-conditioning units (see Figure 2.2) or– In the bypass in air-conditioning ducts.

Equipment protectionEquipment monitoring involves the direct monitoring of an object. These can be unventilated or force-cooled units or cabinets, e.g.– Distributor cabinets, switching cabinets– Telephone-switching equipment– Measuring, control, and regulation equipment.Area monitoring in noise-sensitive areasAll -SL variants are equipped with an extremely quiet fan and can therefore be used in noise-sensitive areas, such as– Hotels– Hospitals– Libraries– Prisons etc.

FAS-420 series aspirating smoke detectors can also be used for early fire detection in areas with special-purpose air conditioning.Its high detection sensitivity enables high value goods and equipment to be monitored. The FAS-420 series is therefore especially suitable for application areas with difficult detection conditions– Where early intervention is essential due to a high concentration value– Where equipment must always be operational– Where highly-sensitive detection is required (e.g. in areas where, due to built-in filter

elements, the air contains a low concentration of smoke particles)– Where high air-exchange rates prevail.

2.3 System OverviewThe smoke aspiration systems comprise an aspirating detector and pipe system.The aspirating smoke detector comprises the detector module for detecting the smoke aerosols, the aspiration unit for transporting the air samples to the detector module and the airflow sensor for monitoring the pipe system for breakage and obstructions.The pipe system comprises essentially pipe and fittings. The standard pipe system is made from PVC or ABS. The pipes used for equipment monitoring should be halogen-free.Each air sampling opening in the pipe system represents a point detector in the planning.

To guarantee reliable operation even under the most difficult conditions (clean rooms, recycling area), there are numerous accessories available, such as air filters, water separators and detonation safety barriers.

2.4 FunctionsAir samples are taken from the area to be monitored using the aspiration unit. They are fed via a pipe system with defined air sampling openings to the sensitive detector module (see Figure 2.4).Detector moduleDepending on the response sensitivity of the detector module in use and programmed alarm threshold, the FAS-420 series aspirating smoke detector triggers the alarm when the corresponding light obscuration threshold is reached. With the FAS-420-TP1 and the FAS-420-TP2, the alarm is displayed via the alarm LED and/or two alarm LEDs on the unit and transmitted to a connected fire panel. The FAS-420-TT1 and FAS-420-TT2 versions offer differentiated LED displays for info, pre and main alarm. Pre and main alarms are transmitted to the fire panel (with FPA-5000 Rel 2.1; additionally with info alarm from Rel 2.5 or above).Various delay times can be programmed for the alarm thresholds, as well as for displaying and transferring malfunctions (see Section 4.3 Settings on the Unit Motherboard, page 67). Alarm messages are saved and are reset after the cause has been eliminated.LOGIC · SENSThe LOGIC · SENS intelligent signal processing compares the measured smoke level with known disturbance variables and decides between alarm and deception. LOGIC · SENS can be activated and/or deactivated using the RPS programming software.Detector module monitoringEach detector module is monitored for contamination, signal malfunction and removal. Soiling of the detector module has no effect on its sensitivity. With all variants, any malfunction is displayed via the malfunction LED and transferred to the fire panel. Malfunctions caused by brief environmental fluctuations can be eliminated with a time-delayed setting.Airflow monitoringAn airflow sensor checks the connected pipe system for breakage and obstruction. The airflow sensor can – depending on the configuration of the pipe system (see Section 3.2 Principles of Pipe Planning, page 33) – detect at least a 50% obstruction to a complete obstruction of the air sampling openings and a breakage in the pipe system that results in a 50% loss from the air sampling openings. Should the fan fail, the airflow in the pipe system is interrupted and this causes a blockage message. Airflow monitoring is temperature-compensated and can be set depending on the air pressure.

On expiry of a defined delay, the malfunction is displayed on the aspirating smoke detector and the message is transmitted to the fire panel. The monitoring window thresholds can be modified to suit the environmental conditions (see Section 3.3 Airflow Monitoring, page 36).The principal signal curve of the airflow sensor is indicated in Figure 2.5.

Fault IndicationAn imminent detector module or airflow malfunction generates a malfunction message that is displayed on the FAS-420. Flash code for malfunction detectionMalfunctions and certain device statues are displayed using various LED flash codes on the detector module's electronics PCB. Thus it is possible to differentiate quickly among malfunctions that can be caused by a defective detector module, an obstruction, or a break in the pipe system.Resetting via fire panelA malfunction message is reset via the connected fire panel. Alarm and malfunction messages are displayed simultaneously on the unit via the Local SecurityNetwork LSN using the reset function on the detector line.Calibrating the airflow sensorAutomatic airflow sensor calibration makes it significantly easier to start the FAS-420. The initialization phase is carried out according to or independently of the air pressure as desired.To set the FAS-420 to the airflow typical for the pipe network, an airflow initialization (flow-init) procedure is carried out. This must be done for each unit once at the start after installation, each time the pipe system is replanned/redesigned and after changing the fan voltage. This enables the unit to determine and save the airflow typical for the pipe network.Pipe systemA pipe system with an overall length of up to 300 m can be connected to FAS-420 series aspirating smoke detectors over a maximum of 32 aspiration points. Two pipe systems can be connected to both the FAS-420-TP2 and FAS-420-TT2 variants. The entire pipe system then has a total length of 2 x 280 m and a maximum number of 2 x 32 aspiration points.

2.5.5 FAS-ASD-DIAG Diagnostic SoftwareThe diagnostic software enables the saved and the current unit status, as well as the error messages to be displayed on the PC or laptop. The supplied diagnostics cable connects the aspirating smoke detector ("DIAG" connection on the motherboard) to the PC. The FAS-ASD-DIAG version is connected to the PC via a USB port, earlier DIAG versions use a COM port (see Figure 2.10). Windows 2000 or Windows XP can be used as the operating system (earlier diagnostic software versions (with serial interface) run under WINDOWS 95, 98, ME, 2000 and NT). For correct color display, the monitor and graphics card must be able to display more than 256 colors.

Figure 2.10 Diagnostic software for reading out device states

Diagnostic messages remain saved in the diagnostic software for at least 3 days in order to be able to evaluate even short, sporadically occurring errors (e.g. in case of changed operating conditions).Resetting the device via the diagnostic software deletes all saved diagnostic messages.The software also allows the deletion of error messages.

2.5.6 Remote IndicatorsA remote indicator must be connected if the aspirating smoke detector is not directly visible or has been mounted in false ceilings or floors.The external detector alarm display must be mounted in an obvious place in halls or entrances of the building section or areas concerned.The display is connected to the unit motherboard via the "X6 ext. Display" (D-/D+/V-/V+). Only digital remote indicators made by Wagner can be used for this connection; these are available by separate order.Alternatively, FNS-420-R LSN Strobes can be connected via LSN and configured via FSP-5000-RPS.

DIAG

NOTICE! The diagnostic software can be used to save all stored and current diagnostics data, as well as the settings made via the RPS programming software as a file. To be able to compare the data read out, save each file under a different file name.




2.5.7 Device Mounting

The MT-1 unit mounting is used if a direct wall installation is not possible, e.g. installation on racks.

2.5.8 Measures for Reducing Operating Noise

Vibration absorbersThe fans of the aspirating smoke detectors cause a noise level of approx. 45 dB(A). Mounting the FAS-420 onto vibration absorbers can effectively reduce noise transmission through the installation elements. This results in a reduction in the noise level from 1 to 2 dB(A).Additional operating noises may be caused by vibrations on the pipe system, which are generated by the air flowing through it. This can be remedied by inserting a corrugated hose (approx. 15 cm long) between pipe system and aspirating smoke detector to create a flexible transition (see Figure 2.12).In noise-sensitive areas, the sound level can also be reduced by installing a piece of plastic pipe approximately 100 mm long into the air outlet opening of the unit. This is done by breaking out the pre-punched opening in the protective grille (e.g. using a small edge cutter).All -SL variants are equipped with an extremely quiet fan that limits the noise level to 38 dB(A). Thanks to the additional sound damper, fan noise can be reduced to 34 dB(A); this ensures that the detector is in accordance with DIN 4109 for living and sleeping areas.

2.6 Pipe System Components

2.6.1 Overview

During planning/design, a distinction is drawn between area monitoring and equipment monitoring. For both applications, PVC and halogen-free pipes can be used , but the restrictions of EN 54-20 must be observed. Halogen-free pipes should be used when monitoring equipment.Figure 2.13 shows essential accessory components that can be selected for the application concerned.The pipe system must be constructed using pipes with an external diameter of 25 mm and the associated fittings.If the maximum permissible pipe lengths are used, then for the pipe returns, pipes with an exterior diameter of 40 mm and the appropriate fittings must be used (see also Section 3.9 Planning for Long Pipe Feed Lines, page 58).Blowing-out systemIn areas that are susceptible to dust particles or icing, it may be necessary to blow out the aspiration pipe system and its air sampling openings. Figure 2.14 shows a manual blowing-out system with a three-way tap.

2.6.2 Air sampling openingsAspiration reducing film sheetsAn air sampling opening is a 10 mm bore in the aspiration pipe that is covered with a patented aspiration reducing film sheet with the required opening diameter. The size of the opening depends on the construction of the pipe system (see Section 3 Planning, page 32).The aspiration reducing film sheet is secured with marking tape to prevent it from becoming displaced. The marking tape is a transparent sticky film with red edges and a 10 mm hole. It is placed over the aspiration reducing film sheet so that the air sampling opening is not concealed and can be seen from long distances.

Aspiration reducing clipsIn areas susceptible to obstructions or icing, special, patented ASD aspiration clips with flexible aspiration reductions are used (see Figure 2.16).

During use in deep-freeze areas, the flexible aspiration reduction expands in the air sampling openings and pushes the ice away during blowing out. The special plastic clip ensures that the aspiration reduction remains at the defined location.

As the clips are more stable under pressure and the elastic rubber insert significantly improves the cleaning effect, they are used for all plans and designs which require a blow-off system due to environmental influences (e.g. increased exposure to dust). The standard AF-x aspiration reducing film sheets and the marking tapes are not suitable for use in low-temperature areas.The aspiration reductions with plastic clips are available separately.

2.6.3 Ceiling Lead-through

A concealed pipe system for area monitoring can be realized by installing in a false ceiling. This requires the use of ceiling lead-throughs in the false ceiling. The ceiling lead-through can be used with a false ceiling thickness of up to approx. 35 mm.According to the planning and design guidelines, the ceiling lead-throughs are fitted with aspiration reducing film sheets with defined air sampling openings and connected to the pipe system by means of aspiration hoses (see Figure 2.17).If these hoses exceed a maximum of 1 m in length, the plan according to Section 3 Planning applies. If structural circumstances dictate that lengths in excess of 1 m are used, the pipe system has to be calculated accordingly.

2.6.4 Air-Return Pipe for Pressure Areas and Atmospheric Loads

If the aspirating smoke detectors and the pipe system are installed in areas with varying air pressure, the aspirated air must be returned to the pressure area of the pipe system (see Figure 2.18). The air-return pipe can serve to equalize pressure or to prevent atmospheric loads (e.g. odors) in neighboring spaces.

The air-return pipe is connected to the air exhaust duct inside the FAS-420 through the ventilation grille (see Figure 2.19). This requires the pre-punched opening in the protective grille to be broken out.

CAUTION! The air-return pipe of the smoke aspiration system should not exceed 2 m. Longer returns must be checked individually.



2.6.5 Water Separator for Humid AreasIf the smoke aspiration system is operated in environments where condensate can form in the aspiration system, a water separator is used. Condensate can form with sharp temperature fluctuations and in areas where fresh air is monitored.

The FAS-ASD-WS Water Separator is integrated at the lowest point in the pipe system upstream of the air filter and the aspirating smoke detector. The 45° pipe elbow permits optimum distance from the wall (see Figure 2.20).The FAS-ASD-WS Water Separator can be operated in a temperature range from 0 °C to +50 °C. The sintered metal filter in the water separator has a pore width of 50 µm and causes an additional rough absorption of soil particles.The FAS-ASD-WS is supplied with an angle support and PG cable glands. The 45° pipe elbows (4 units) must be ordered separately.

2.6.6 Detonation Safety Barrier for Potentially Explosive Areas

Vapor/air and/or gas/air mixture ignition in the aspirating smoke detector may result in pipe explosion or detonation. This depends on the composition, concentration, temperature, and pressure of the flammable mixture.The detonation safety barrier is a flame trap that is flame-proof in the face of pipe explosions (deflagrations) and detonations (see Figure 2.21).In normal operation, the steam and gas mixtures flow in any direction through the safety barrier. An ignition of the mixture in the upstream aspirating smoke detector will cause the developing detonation to be arrested. Ignition is prevented by the flame filter. Combustion of the mixture in the flame filters may cause a rebound of the detonation front. To prevent this, a minimum pipe length of 1.0 m between the installation point of the detonation safety barrier and a possible ignition source (aspirating smoke detector) must be maintained. Permanent fire prevention is thus achieved indirectly.

3.1 RegulationsThe planning regulation below is based on the system limits of FAS-420. The applicable national regulations of the countries concerned must be observed and the plans modified accordingly.The planning for the aspirating smoke detector in accordance with EN 54-20 is described below. The basic conditions are specified in Section 3.1 Regulations. Planning must be carried out in accordance with Section 3.6 Standard Pipe Planning. In addition to 3.6 , special applications are also bound by the restrictions of the planning notes in accordance with Section 3.7 Pipe Planning for Single-Hole Monitoring and the following sections. These must be taken into account from the start in the case of any special planning processes.Planning options in accordance with EN 54-20:Various technical solutions are available to suit different planning criteria. The following table lists the chapters in which the solutions are described.

– The guideline "Installation protection for electrical and electronic systems" VdS Schadenverhütung GmbH, Cologne (VdS 2304)

– The "Planning Aspirating Fire Detectors" data sheet from VdS Schadenverhütung GmbH, Cologne (VdS 3435)

The applicable national regulations must also be observed, for example in Germany:– DIN VDE 0833 parts 1 and 2 "Alarm systems for fire, intrusion and hold-up"– Additional provisions for the installation of fire detection systems, which are published

by fire directors of fire departments, by the construction supervision authorities or by the construction law authorities that have only local validity.

3.2 Principles of Pipe PlanningThe aspiration pipe network must be designed such that all possible fires in the monitoring area can be dealt with at an early stage.The number of air sampling openings and the structure of the pipe system depend on the size and geometry of the monitoring range. The pipe system must be laid out according to the planning guidelines in this chapter, taking into account the following issues:Symmetrical structureThe pipe system should preferably have a symmetrical structure, i.e.– Same number of air sampling openings per pipe branch– Same pipe branch lengths (should not exceed ± 20% deviation)– Same distance between neighboring air sampling openings on the smoke aspiration pipe

(should not exceed ± 20% deviation).Asymmetrical structureIf structural circumstances dictate that the pipe system is to be designed asymmetrically (see Figure 3.1), the following conditions apply:– The number of air sampling openings and the length of the shortest and longest pipe

branch within the pipe system must not exceed a quantity ratio of 1:2.– The distance between neighboring air sampling openings on the smoke aspiration pipe

must be equal (should not exceed ± 20% deviation).– The diameters of the air sampling openings are determined separately for each pipe

branch. The diameters depend on the total number of air sampling openings in the pipe branch in question.

Figure 3.1 shows a typical U-pipe system with three or six air sampling openings and the air sampling opening diameters calculated according to Section 3.6 Standard Pipe Planning.

NOTICE! – For planning, the system limits in accordance with Section 3.5 Planning Limits are to be

observed.– Select airflow monitoring and the associated planning limits (see Section 3.3 Airflow

Monitoring) and check these for any restrictions imposed by country-specific regulations.– If the on-site planning deviates from the standard plans described below, this must

always be checked with activation attempts for correct detection of a malfunction and a fire. A special plan may be required.

– Plans not contained in the operation guide must be requested.



Pipe diameterAs a rule, the pipe system is created using pipes with a 25 mm diameter. Both PVC pipes and halogen-free pipes can be used, however, ensure that you comply with the restrictions of EN 54-20. Halogen-free pipes are to be used in preference for equipment monitoring.In many applications, greater distances between the aspirating smoke detector and the aspiration pipe must be bridged. This is done using pipes with greater diameters (40 mm), which guarantees maximum planning (see also Section 3.9 Planning for Long Pipe Feed Lines, page 56). However, pipes with greater diameters restrict the length of the pipe system.Longer pipe feed linesBranch lengthTo achieve short transport times for the smoke aerosols in the aspiration pipe and thus quick detection, it is better to plan several short branches than fewer long ones (preferably U and double U-pipe system).Pipe configurationsDepending on the area geometry, five pipe configurations can be selected (see Figure 3.2):– I-pipe: pipe system without branches.– U-pipe: pipe system that branches into two pipe branches.– M-pipe: pipe system that branches into three pipe branches.– Double U-pipe: pipe system that branches symmetrically into four pipe branches.– Quadruple U-pipe: pipe system that branches symmetrically into eight pipe branches.

Change of directionElbows and bends in the pipe system increase flow resistance. Therefore, they should only be used where they cannot be avoided for structural engineering reasons.

If elbows or bends are used, the maximum total length of the pipe system is reduced.

Special casesIf the pipe system does not correspond to the planning guidelines described here owing to structural circumstances, it must be calculated separately for the case in question on request.TestingFor critical applications, test the secure detection with activation attempts. Check also whether there is airflow at the individual air sampling openings.

NOTICE! It is preferable to use pipe bends rather than pipe elbows.The detection time will be influenced significantly by too high a number of changes of direction.

NOTICE! In order to increase transport speed in critical application areas, the fan voltage can be increased from 6.9 V to 9 V.



One aspiration line must be assigned per detector module. Both detector modules of a device must be evaluated independently of one another. Only one extinguishing area per smoke aspiration system may be monitored.

Two alarm stagesTo implement two alarm stages, a pipe adapter for the aspiration pipe system is required. The two detector modules in the aspirating smoke detector require different response sensitivities.

3.3 Airflow MonitoringEN 54-20 requires the detection of a 20-percent change in the airflow volume by the detector module's airflow sensor. In order to achieve this, the activation threshold of the airflow sensor must be set to level II. Alternatively, level I can also be used. It is recommended that airflow calibration is carried out dependent on air pressure for both of these settings. In systems that do not need to comply with EN 54-20, any threshold can be set. The smoke aspiration pipes are planned taking into account the applicable national regulations for the country concerned.Adapting the airflow sensitivityThe sensitivity of the airflow sensor must be adapted to the application. For example, a long pipe system requires a sensitive setting of the airflow sensor. The activation threshold and thus the sensitivity of the airflow sensor can be set on 4 levels. Breakages and obstructions must be accurately detected in the event of a malfunction.

Dynamic airflow sensorsThe airflow monitoring of the unit makes it possible to detect breaks at the end of pipes and identify sudden obstruction of individual air sampling openings (e.g. following tampering with the pipe system). Because these dynamic airflow sensors are only active if level I was selected for the airflow monitoring, the points outlined under "Level I restrictions" must be taken into consideration.RestrictionsAirflow monitoring may only be set to level I if – planning was carried out in accordance with "single-hole monitoring" (see Chapter 4.3.1

"Pipe Planning for Single-Hole Monitoring"), – the airflow sensor was calibrated dependent on the air pressure (see Chapter 7.1.2

"Airflow Calibration according to Air Pressure") – and no larger airflow fluctuations can occur.Air pressure differencesThere must be equal air pressure along the length of the aspiration pipe.

3.4 Defining the Response SensitivityThe sensitivity of smoke aspiration systems can be divided into certain fire sensitivity classes in accordance with EN 54-20. These fire sensitivity classes describe specific examples of ways in which the systems can be applied. The permissible system plans given in Section 3.6 can be determined for each classification.Smoke aspiration systems with a higher fire sensitivity class according to EN 54-20 also satisfy the requirements of the lower classes.

Level I II III IV

Complies with EN 54-20

Activation threshold Small Average Large Very large

Sensitivity Very high High Average Low

NOTICE! Selection of the largest possible, precisely still-approved level is recommended.

NOTICE! If the aspirating smoke detectors and the pipe system are positioned in areas with different air pressures, the air aspirated by the FAS-420 must be returned to the pressure area of the pipe system (see Section 2.6.4 Air-Return Pipe for Pressure Areas and Atmospheric Loads, page 24).

The planning of the monitoring area always occurs according to the national guidelines for point-type smoke detectors.

3.5 Planning LimitsThe following limit values must always be observed for the FAS-420 series:

The maximum monitoring area of an air sampling opening corresponds to the monitoring area of point-type detectors in accordance with the applicable planning guidelines.The maximum total monitoring area, the maximum total pipe length and the maximum number of air sampling openings depend on the selected planning. They are also dependent on the restrictions imposed by national regulations.Depending on the planning selected, some restricted values may apply.The values for the maximum number of air sampling openings, the maximum pipe length and the maximum overall monitoring areas apply for each pipe system. Two pipe systems can be connected to aspirating smoke detectors FAS-420-TP2 and FAS-420-TT2, each with two detector modules.

NOTICE! Depending on the number of air sampling openings, fire sensitivity classes A, B and C can all be achieved with the detector modules available.

3.6 Standard Pipe PlanningIn order to plan in accordance with the EN 54-20 standard, certain factors must be known, such as the system sensitivity requirements, the number of air sampling openings and the accessories needed for the application concerned. These factors can be used to determine the appropriate standard-compliant construction of the pipe system using the following chapter and the planning table in the appendix.

3.6.1 Determining the Necessary AccessoriesAs accessory components, e.g. filters, have a particular effect on the dimensions of pipe planning, the appropriate accessory must be selected for the application concerned in advance. Retrofitting an accessory, e.g. a fine filter, is largely only possible if a sensitive detector module is used or if a certain contingency is planned in advance.The following components must be taken into account in this regard:– Air filter– Water separator– Three-way-tap– Detonation safety barrierSee Section 2.8.4

3.6.2 Pipe Planning with Pipe AccessoriesFor the purpose of pipe system planning, the following planning table is available for all selected pipe accessories.– Planning without air filter– Planning with FAS-ASD-FL air filter

NOTICE! In order to improve the detection quality of a smoke aspiration system, an area can be monitored with more detection points than required by national guidelines. However, to calculate the necessary sensitivity of an aspirating smoke detector, the number of aspiration points required by the standard must be used.



ProcedureIn the following example, a plan without air filter with 8 openings should satisfy class B if a water separator is also used. The red shaded areas show the potential plans with different pipe shapes and fan voltage.

3.9 Planning for Long Pipe Feed Lines

Pipes with a 40 mm diameter are required for planning pipe feed line A (Figure 3.18). Area B is designed with 25 mm pipes in accordance with Section 3.6 Standard Pipe Planning. The plan applies for the pipe configurations described above.

The general pipe planning is restricted by the use of long pipe feed lines as follows:– Pipes with a 40 mm diameter increase transport time. – 1 m pipe with a 40 mm diameter replaces 3 m pipe with a 25 mm diameter.

A basic pipe can be installed for high-rise warehouse (Figure 3.19) planning, from which the stub-shaped aspiration pipes are routed.

3.10 Planning with Acceleration OpeningsAcceleration openingsIn order to meet individual regulations, it may be necessary to increase the transport time of the systems. This can be fulfilled by fitting the ends of the pipe branches with acceleration openings, which increase transport speed. Depending on the regulations concerning transport time, it may be necessary to dimension an acceleration opening with the same or double the diameter of the last air sampling opening on a pipe branch. Only authorized aids should be used to calculate the transport time.The additional airflow of the acceleration openings also reduces the sensitivity of the air sampling openings. If required, this reduction can be offset as follows:

1. option: increasing the sensitivityReduced sensitivity at the air sampling openings can be offset by using a more sensitive detection setting. A distinction must be made regarding whether the cross-section of an acceleration opening is smaller or the same as:– the cross-section of the last air sampling opening of a branch (Table 3.1)– the doubled cross-section of the last air sampling opening of a branch (Table 3.2)

Table 3.1 Factors for increasing the sensitivity (acceleration opening corresponds to one air sampling open-

ing)

Table 3.2 Factors for increasing the sensitivity (acceleration opening corresponds to two air sampling open-

ings)

Example:A class B double U-pipe system with 24 air sampling openings is planned. According to EN 54-20, 24 openings are permitted in class B at a sensitivity of 0.25% LT/m. In order to increase the transport time, an acceleration opening the same size as the last air sampling opening is to be used.According to Table 3.1, the necessary sensitivity of the detector module in this case is 0.25 % LT/m * 0.85 = 0.1875 % LT/m.

2. option: reducing the number of air sampling openingsReduced sensitivity at the air sampling openings can be offset by reducing the number of air sampling openings. A distinction must be made regarding whether the cross-section of an acceleration opening is smaller or the same as:– the cross-section of the last air sampling opening of a branch (Table 3.3)– the doubled cross-section of the last air sampling opening of a branch (Table 3.4)

3.11 Planning for Forced AirflowMonitoring the air-conditioning ductsAir-conditioning units are broken down into low and high-speed units (see table below). The details provided in this chapter apply only to low-speed units. There are no adequate empirical values available for high-speed units. Hence, smoke trials must be executed for air-conditioning ducts with flow speeds above 10 m/s, in order to determine optimal response behavior.

The speed distribution in an air-conditioning duct appears as follows:

The exhaust duct should be selected as the installation location of the pipe system, as far as possible away from the sound dampers, air baffles and bends. The distance from such “obstacles” should be at least three times the smallest duct diameter. If it is absolutely essential to install the pipe system directly behind air baffles, sound dampers or bends; the main speed ranges must be monitored (see Figure 3.21/Figure 3.22).

When installing a pipe system in air-conditioning ducts, the following must be observed:– Since the FAS-420 and the pipe system are located in different pressure ranges, an air-

return pipe (see next page) must be provided.– The pipe entries into the duct must be airtight.– The portion of the pipe system that is outside the duct must be sealed airtight.

Air-return pipeThe air-return pipe must be positioned at a distance of at least 2 m from the aspiration. The open end of the return is sloped at a 45° angle (see Fig. 5.5, page 80).

If the distance of 2 m cannot be adhered to, the pipes must be arranged offset. This way, a pressure fall between intake and exhaust can be achieved since the pipes are located in different speed ranges (see Figure 3.24).The distance of the air sampling openings to one another and to the duct wall is represented in the following table.

Diameter of the air sampling openingsThe diameter of the air sampling openings is derived from the number of air sampling openings. The precise value can be obtained from Section 3.8 Simplified Pipe Planning.

3.12 Power SupplyTo measure the power supply, the detector-ready state of the security system and the alarm case are regarded. When the system is ready to detect, the power supply must provide the standby current for the aspirating smoke detectors and ensure the emergency power rechargeable battery is charged in accordance with DIN VDE 0833, part 1 (80% charged in 24 hrs). Current calculationThe current in the event of an alarm is calculated according to the following formula:Space protection

Equipment protection

Charging currentThe current required to charge the battery is calculated using the formula below (for space and equipment protection):

The power supply can service detectors from several detection ranges, e.g.:– 1 x FAS-420 in detection zone 1– 2 x FAS-420 in detection zone 2– 4 x FAS-420 in detection zone 3– 1 x FAS-420 in detection zone 4 etc.In the example, the zone with the highest energy requirement is zone 3 and hence nmax = 4.

For equipment protection, it is assumed that max. √n detectors can trigger an alarm at the same time.

Please refer to Section 2.8 Technical Specifications, page 29 for the current consumption of the FAS-420.

whereIg = Total current of all connected aspirating smoke detectors in [A]IA = Alarm current of an aspirating smoke detector in [A]IQ = Standby current of an aspirating smoke detector in [A]IPSmax = Max. power supply of the network power supply in [A]IL = Charging current of the rechargeable batteries (80% of the nominal capacity

Ig = IA x nmax + IQ x (n - nmax) ≤ IPSmax

Ig = IA x √n + IQ x (n - √n) ≤ IPSmax

IL = 0,8 x Kn

24

Ig = IQ x n + IL ≤ IPSmax

NOTICE! The power packs are laid out using the calculated total current (Ig) with the highest value.


Planning | en 63


Line calculationThe maximum line length is derived from the permissible voltage drop on the supply line. The permissible voltage drop is the difference between the end-point voltage of the backup battery (21.5 V) and the lower operating voltage limits of the aspirating smoke detectors.

To guarantee the impermeability of the housing, the corresponding cable bushing must be selected for the existing cable.– M 25 cable bushing: Ø 9-14 mm– M 20 cable bushing: Ø 8-12 mmThe Fire System Designer (FSD) enables case-specific calculations to be carried out for planning the FPA-5000 Modular Fire Panel.

4.3.2 Setting the Fan VoltageThe standard fan voltage setting is 6.9 V. In critical applications, the fan voltage may be switched to 9 V. This increases the transport speed in the pipe system, thus achieving faster detection with longer pipe lengths.To switch to 9 V, pull out jumper BR4 (see Figure 4.2).The default setting is marked in bold.

4.3.3 Setting the Fan Voltage (SL Variant)For FAS-420-xx systems, the standard fan voltage setting is 6.9 V.

The fan voltage on the fan activation circuit board on SL devices is set using the jumpers BR1 and BR2. The default setting is marked in bold.

4.3.4 Number of Detector ModulesThe number of populated detector modules is factory set depending on the model variant (jumper BR1 on the motherboard, see Figure 4.2).

4.4 Installing the Unit

The air outlet on the unit must not be obstructed. There must be a free area of 10 cm in front of the air outlet.The aspirating smoke detector can be installed with the aspiration device pointing upwards or downwards. Rotate the cover through 180° in the required direction. Aspiration downwardsIf the air-return pipe is directed upwards, it must be guaranteed that no foreign bodies or dripping water can penetrate the air return. You should therefore use a short, downward angled pipe (see Figure 4.3).Mounting type MT-1The aspirating smoke detector is either bolted directly to the wall provided for installation using the rear panel or installed by means of unit mounting type MT-1, e.g. onto frames (see Figure 4.4).

Reducing operating noisesIf the aspirating smoke detector is installed in noise-sensitive areas, observe the instructions in Section 2.5.8 Measures for Reducing Operating Noise, page 20.

Installation1. First, clearly mark the fixing points on the installation position provided on the

equipment. Use the supplied drilling jig as an aid. To guarantee a safe and low-vibration hold, the unit must be secured with four screws.

2. Using four screws appropriate for the installation method, attach the unit securely to the surface or to the unit mounting. Ensure that the unit is not fixed under mechanical stress and that the screws are not tightened too tightly, otherwise damage or undesirable resonance noises could occur.To equalize unevenness and/or prevent vibrations, vibration absorbers (subject to separate order) must be used..

Connecting the aspiration pipe1. To connect the aspiration pipe to the FAS-420, insert it into the pipe connection provided

(see Figure 4.7).

4.5 Connection to the Fire Panel

4.5.1 Electrical Connection

Proceed as follows to prepare the electrical connections:1. Using a screwdriver, carefully punch out the required cable entry points of the housing

(max. 5 x M20 and 2 x M25).2. Fit the cable entry point(s) as required with M20 or M25 connections by pushing them

into the cable entries. 2 x M25 and 1 x M20 are supplied in the pack.3. Punch out the connections using a sharp object.

Caution: Do not cut the cable bushings with a knife!4. Route the connection cable(s) (max. 2.5 mm2) through the prepared M20 or M25

connections and into the unit. Now cut these to the required length inside the unit.5. Wire the unit according to the connection information described below. The connection

terminals of the 24 V additional supply voltage and the LSN connection are plug connections and are easy to remove.

NOTICE! – Do not use glue to connect the aspiration pipe and pipe connection.– In the event of sharp temperature fluctuations, the pipe must be fixed immediately in

front of the unit so that the pipe does not pull out of the pipe connection when the length changes (see Section 5.1 Length Change of the Pipe System).

CAUTION! Switch off the unit before carrying out any connection work!

NOTICE! The units are usually connected to an additional power supply. When connecting to the FPA-5000 Modular Fire Panel, the voltage is supplied via the AUX outputs of the BCM 0000 Battery Controller Module. Alternatively, an external power supply unit (e.g. FPP-5000 or UEV 1000) can be used.

4.5.2 LSN ConfigurationOnce the aspirating smoke detector has been connected to the LSN, the detector and detector module, or the two detector modules (FAS-420-TP2 and FAS-420-TT2), are configured using the FSP-5000-RPS programming software via a laptop connected to the FPA-5000 Fire Panel. Information on the LSN configuration can also be found in the Online Help feature of the RPS programming software. Notes on diagnostics data for the fire panel are contained in the operation guide for the FPA-5000.

4.5.3 Parameter Settings via RPS (Remote Programming Software)The parameters for each detector module are specified in the relevant "Sensor" dialog window via drop-down fields. The defaults settings in RPS are marked in bold.1. Enter the used detector module.2. Select all other parameters (see tables).

NOTICE! Both a dual-detector dependency and a dual-zone dependency can be established when connecting the FAS-420-TP2 and the FAS-420-TT2 to the FPA-5000 Modular Fire Panel.

Higher values are not permitted within EN 54-20.



4.6 Connecting an External Detector Alarm DisplayA digital external detector alarm display can be connected to the 420 series aspirating smoke detectors. This is available by separate order. Connect the remote indicator to the motherboard of the FAS-420 using the terminal strip X6 (see Figure 4.2, Page 65). The unit must be in a voltage-free state for this. Alternatively, FNS-420-R LSN Strobes can be connected via LSN and configured via FSP-5000-RPS.

4.7 Data Logging

The DIAG diagnostic software is used to conduct the device tests.The current airflow sensor data, smoke level values, various status values and the parameters configured via RPS can be read out locally using a laptop. This makes it much easier to detect altered operation conditions in the event of service being carried out.The supplied diagnostics cable connects the aspirating smoke detector ("DIAG" connection on the motherboard) to the PC. The FAS-ASD-DIAG version is connected to the PC via a USB port, earlier DIAG versions use a COM port (see Figure 4.8).Windows 2000 or Windows XP can be used as the operating system (earlier diagnostic software versions (with serial interface) run under WINDOWS 95, 98, ME, 2000 and NT). For details, please see the diagnostic software documentation.

74 en | Installation of the Pipe System FAS-420 Aspirating Smoke Detector LSN"improved version"


5 Installation of the Pipe SystemAt the very least, the pipes and fittings used for the pipe system must comply with class 1131 according to EN 61386-1, 2004.Class 1131 requires the following of the pipe system in use:

The pipe system must be constructed using the following pipes and the associated fittings:

For pipe systems with long pipe feed lines (see also Section 3.9 Planning for Long Pipe Feed Lines, page 56), you must also use the following pipes and the associated fittings:

The pipe system must be constructed according to planning specifications and taking into account the planning guidelines (see Section 3 Planning).1. Shorten the pipes with a pipe-cutter (38 mm) or a metal saw. Deburr the joints and clean

up the chips.2. Before gluing, clean the adhesion points with the prescribed cleaning agent (Tangit) to

remove dirt and grease. Use the Tangit adhesive to glue the pipe transitions with the appropriate fittings so that they are airtight.

3. Minimize pipe lengths and changes of direction. Pipe elbows have an extremely high flow resistance. Therefore, they should be used only where they cannot be avoided for structural engineering reasons. If necessary, reduce pipe lengths in proportion to the pipe elbows used.

4. Fix the pipe system. It must not sag or be possible to move it. Fasten the pipes with pipe clips without rubber inserts. The distance between the pipe clips should not exceed 80 cm. At high temperatures, reduce the distance between the pipe clips to a maximum of 30 cm.

NOTICE! When constructing the pipe system, observe the temperature range specified under Section 2.8.3 Pipe system, page 30 in the Technical Specifications chapter.

NOTICE! If halogen-free plastics must be used, the installation procedures may vary depending on the selected material: – ABS is glued– Polypropylene (PP) is welded– Polyamide (PA) is pushed together and bolted.

NOTICE! Pipe bends must be given preference over pipe elbows. Too many changes of direction can cause an airflow malfunction in the FAS-420 and have a negative impact on the detection time.As a benchmark, a pipe bend corresponds to a straight pipe length of 0.3 m. An elbow corresponds to a straight pipe length of 1.5 m.

5. Close open pipe ends with an end cap.

5.1 Length Change of the Pipe SystemLength changes to the pipes are caused by temperature changes. Temperature increases cause lengthening of the pipes, temperature drops cause shortening of the pipes. The length change must be given particular consideration if the temperature of the pipe system at the time of installation deviates from the normal operating temperature.The length change can be calculated using the following formula:ΔL = L x ΔT x δ

For example, a temperature change of 10 °C on a 10 m-long PVC pipe causes a length change of 8 mm.Mounting clampsPVC pipe clips are used as standard for installing the pipe system. These clips do not allow any length extensions.

NOTICE! Do not use pipe clips with rubber inserts since these do not allow length extensions and the pipe system may bend or even tear.

NOTICE! On completion, test the pipe system: – For leaks – For fault-free connections– For correct planning of the air sampling openings.

5.3 Ceiling Lead-through

The following steps are essential for installing a ceiling lead-through:1. Before gluing, clean the adhesion points with the prescribed cleaning agent to remove

dirt and grease. Glue the hose connection to the relevant T-fitting on the aspiration pipe using Tangit adhesive.

2. Drill a ∅ 13 mm hole in the false ceiling for each ceiling lead-through.3. Install the ceiling lead-through by removing the nut, pushing the part with the hose nozzle

through the bore from below, then refitting and tightening the nut above the false ceiling.4. Determine the required aspiration hose and cut to length. Place the cut end of the hose

onto the hose nozzle in the ceiling lead-through and onto the hose connection on the aspiration pipe T-fitting. If necessary, heat up the hose using a hot air blower.

5. Glue the required aspiration reducing film sheet (as per the planning guidelines) onto the ceiling lead-through.

NOTICE! The holes of the aspiration reducing film sheet and the marking tape must be exactly over the aspiration boring so that the opening diameter of the aspiration reducing film sheet is not changed.To keep the adhesive surfaces of the film sheets free of dust and grease, avoid touching them.

5.5 Air Filter

5.5.1 Installing the Air Filter Box

Air filter box1. To use the filter box in the pipe system, use the two PG29 filter screw connections

supplied.2. Install these screw connections precisely as for the pipe adapter.3. When installing the filter, note the throughflow direction, which is specified on the type

plate on the side of the lower part of the housing.4. Screw the air filter housing directly onto the wall with the lower part of the housing.Installation materialCylinder or flathead screws are suitable for wall mounting:

– Maximum thread diameter: 4 mm– Head diameter: 5 to 7 mm.

5.5.2 Filter Change on the Air Filter Box

To replace the filter inserts, proceed as follows (see Figure 5.7):

1. Loosen the four screws and remove the housing cover from the filter box.2. Remove the old filter inserts and clean the inside of the housing carefully to remove dust.

Now fit the cleaned or new filter inserts. When using the spare filter set for the large air filter box, ensure you follow the correct sequence (see label on base of housing).Replace the housing cover and screw it back on.

5.6 Air-return Pipe

Fix the air-return pipe within the air exhaust opening. No additional components are required.

Steps:1. Remove the pre-punched pipe opening in the protective grille of the air exhaust opening

(e.g. using a small edge cutter).2. Insert the air-return pipe through the opened pipe opening in the protective grille and fix

it to the FAS-420 with the rubber ring already integrated into the air-exhaust opening.

NOTICE! In applications with largely fine dust build-up, three fine dust filters can also be used (subject to separate order).

CAUTION! In the event of sharp temperature fluctuations, the pipe must be fixed immediately in front of the unit so that the pipe does not pull out of the pipe connection due to length change (see Section 5.1 Length Change of the Pipe System).




5.7 Three-way Tap

The three-way tap is required to blow out the pipe system with blast air (as a preference) or compressed air (compressed air is compressed, non-purified and humid ambient air. Blast air, in contrast, is purified and dehumidified air. If the FAS-420 and pipe system are located in areas with temperatures below freezing, blast air is to be used for blowing out). The aspirating smoke detector and the downstream pipe system accessory components (e.g. air filter) must not and cannot be blown-out.A check valve for relieving pressure from the pipe system must be fitted to the end of each pipe branch. The check valve prevents damage to the air sampling openings and prevents dirt deposits from being blown through the pipe system. To prevent aspiration reducing film sheets in deep-freeze areas from tearing, it is advisable to use special deep-freeze aspiration reductions.Check valve and deep-freeze aspiration reductions are available on separate order.ConnectionsFasten the three-way tap using the transition screw connections in the pipe system.During installation, note the assignment of the connections:– Install the aspiration pipe system on connection C.– Install the FAS-420 on connection A.– Attach the compressed air supply (compressor or mobile blowing-out system) to

connection B of the three-way ball valve.

The manual blowing-out process on the pipe system is carried out as follows:

NOTICE! A single blowing-out process can be completed within 50 seconds. If within this time the unit is still connected to the pipe system, the malfunction message “airflow sensor module malfunctioning” will not be evaluated. If the blowing-out process has to be repeated (steps 1 to 3), wait at least 120 s.



1. Position the tap lever so as that the blast air and pipe system (B-C connection) are connected.The connection to the FAS-420 must be blocked for blowing-out!Manually blow out the pipe system for approximately 10 seconds.

2. Set the lever of the tap such that the device is not connected with the pipe system or with the connection for the blast or compressed air supply. Wait approximately 20 seconds so that dust and dirt raised in the pipe system can settle and thus will not be sucked through the aspirating smoke detector.

3. Reconnect the blown-out pipe system to the FAS-420 within a further 10 seconds by switching the tap accordingly (A-C connection).

5.8 FAS-ASD-WS Water SeparatorThe FAS-ASD-WS Water Separator must be fitted at the lowest point in the pipe system downstream of the air filter and the aspirating smoke detector (see Figure 5.10).

Attach two 45° pipe elbows on both sides (not supplied as standard) in order to achieve the optimum distance from the wall for mounting the brackets. When installing, note the correct direction of flow (see arrow on plastic container).Also fasten the water separator with two screws and the clamp.To empty, open the drain valve (see Section 7.8 Maintenance Intervals, page 97).

5.9 Detonation Safety Barrier

The detonation safety barriers are integrated into the pipe system and the air return at a minimum distance of 1 m from the aspirating smoke detector. The detonation safety barrier is glued to the FAS-420 on the side of the pipe system or the air-return pipe via a transition screw connection and connected to the side of the unit via a steel pipe (see Figure 5.11). The connection between detonation safety barrier and steel pipe/transition screw connection is made using a ¾" screw connection.

5.10 Test Adapter

For test purposes, the pipe system connection is simply pulled out and the test pipe connected directly to the aspirating smoke detector. However, this is not possible if the aspiration pipe system has to be permanently mounted. A test adapter should be used for this application.

6 Commissioning

6.1 PreparationChecking the settingsCheck the settings of the FAS-420 (Section 4.3 Settings on the Unit Motherboard, page 67) prior to commissioning. Then connect the unit to the power supply. The detector module of the FAS-420 is ready for operation after approximately 1 minute.To commission the FAS-420, completely install the pipe system and connect it.Connection testCheck whether… 1. The correct aspiration reducing film sheets are glued to the air sampling openings.2. The pipe system is securely connected to the FAS-420 pipe connection.3. All pipe fittings are glued together and the pipe system is sealed.

To do this, first close all air sampling openings (e.g. with duct tape). Now measure the negative pressure using a digital pressure gauge (see Section 6.6.2 Conducting the Functional Test, page 90)– Either at the opening for the return airflow – Or using a test adapter installed directly upstream of the unit in the aspiration pipe

(see Section 5.10 Test Adapter, page 85).After a short run-up time, the negative pressure must lie within the following range:

– Fan voltage 6.9 V: 250 Pa to 310 Pa– Fan voltage 9 V: 460 Pa to 530 Pa.

FAS-ASD-DIAG Diagnostic SoftwareThen check the system using the DIAG diagnostic software.Follow the procedure below:1. Install the diagnostic software on a laptop or PC (for details on system requirements and

connection, see Section 4.7 Data Logging, page 74).2. The FAS-420 is connected to the PC via the "DIAG" port on the motherboard using the

supplied diagnostics cable.3. The diagnostic software is started.The current FAS-420 data is displayed on the PC's screen.FPA-5000 diagnostics dataNotes on diagnostics data for the fire panel are contained in the user guide for the FPA-5000.

NOTICE! For a later evaluation of the airflow value, record the calibration type (see Section 6.2 Calibrating the Airflow Sensor, page 86), start-up temperature, air pressure and height above sea level in the test log (see Section 8.5 Test Log for Aspirating Smoke Detectors in the FAS-420 Series, page 110).Once the airflow sensor has been calibrated, no further changes may be made to the pipe system.If changes are necessary at a later time, the airflow sensor must be re-calibrated (see Section 6.2 Calibrating the Airflow Sensor).

6.2 Calibrating the Airflow Sensor

Described below is the procedure for calibrating the airflow sensor, both irrespective of air pressure, i.e. in simplified form, and depending on air pressure. Restrictions for the simplified procedure are contained in Section 3.3 Airflow Monitoring, page 36.For an air-pressure-dependent calibration, use the air pressure correction tables in the appendix (Section 8.2 Air Pressure Correction Tables for Airflow Sensor Calibration, page 105).To be able to judge the airflow sensor value correctly during start-up work, always adhere to the type of calibration in the test log.

6.2.1 Air-Pressure-Independent Calibration

1. Make sure that the aspirating smoke detector has been operating for at least 30 minutes.2. To initialize the connected pipe system, press the S2 flow-init button on the detector

module concerned (see Figure 6.1), until the green operating LED on the unit starts to flash. Initialization is complete after approx. 5 s. Following successful initialization, the operating LED lights up permanently.

3. Connect the housing to the FAS-420 and check that it is correctly positioned.No further modifications may be made to the pipe system during or after initialization. The fan voltage must also remain unchanged following initialization. Otherwise, the initialization procedure must be repeated.

NOTICE! The aspirating smoke detector must be operated for at least 30 min prior to the airflow being initialized to bring it up to operating temperature.

NOTICE! If initialization is not successful, the unit reports a collective fault (fault relay drop off). The precise cause of the abort can be read out using the DIAG Diagnostic Software.




6.2.2 Air-Pressure-Dependent Calibration

A barometer (recommended: GPB 1300 digital precision pocket barometer from Greisinger electronic GmbH) and a multimeter are required to calibrate the airflow sensor dependent on air-pressure. The following steps are required:1. Make sure that the aspirating smoke detector has been operating for at least 30 minutes.2. Determine the height above sea level, air pressure, and ambient temperature of the

installation location and enter these values in the test log.3. Use the air pressure correction tables (see Appendix Section 8.2 Air Pressure Correction

Tables for Airflow Sensor Calibration, page 105) to bring the calibration value in line with that of the airflow sensor. Also enter these values into the test report. When selecting the air-pressure-correction table, take the pipe planning into account

4. Remove the "X6 ext. Display" connection terminal from the motherboard. Connect the multimeter to the measuring points MP2 (+) and MP3 (-) (see Figure 6.2). Note the polarity. On the measuring device, select the "V-DC" range. The default voltage at the measuring points is 1.2 V.

5. Using the trimming potentiometer, set R53 to the calibration value from the air-pressure-correction table with the help of a small screwdriver. Reinsert the "X6 ext. Display" connection terminal into the motherboard.

6. Connect the FAS-420 housing and check that it is correctly positioned.

6.3 Testing the Detector Module and Alarm Transmission

1. Detach the detector module using test aerosol. Spray the test aerosol either into the first air sampling opening or into the test adapter on the pipe system.

2. Use the table below to check the transmission line to the fire panel.

6.4 Checking Malfunction Transmission

Malfunction transmission occurs as part of checking the airflow monitoring system (as per section below).Check whether, when a pipe breakage and an obstruction are detected, the malfunction is displayed at the aspirating smoke detector and at the fire panel.

6.5 Checking Airflow MonitoringPipe breakageCheck the breakage detection:1. Detach the pipe from the connection to the FAS-420 or open the test adapter.2. Check whether the malfunction display on the aspirating smoke detector lights up.3. Check the data of the airflow sensor using DIAG Diagnostic Software and a PC or laptop.4. Check whether the malfunction is displayed on the fire panel.5. Enter the results into the test log.ObstructionCheck the obstruction detection:1. Close – depending on the planned airflow monitoring – the corresponding number of air

sampling openings with some duct tape. 2. Check whether the malfunction display on the aspirating smoke detector lights up.3. Check the data of the airflow sensor using DIAG Diagnostic Software and a PC or laptop.4. Check whether the malfunction is displayed on the fire panel.5. Enter the results into the test log.

TroubleshootingIf the airflow malfunctions are not correctly detected by the unit, proceed as follows:Check whether…1. All inlet holes are free2. The pipe system has breaks or fractures

Check… If this is not the case, ...– Whether the alarm is displayed on the

aspirating smoke detector– Check whether the display board is

connected– There is a fault with the aspirating smoke

detector Replace the detector module– Whether the alarm is transmitted to the

fire panel and reported on the appropriate line

– Check the transmission lines

NOTICE! The steps below may only be carried out following an airflow calibration in accordance with Section 6.2 Calibrating the Airflow Sensor.

NOTICE! A pipe breakage or pipe obstruction is indicated by a flash code via an LED on the detector module (see Section 7.2 Flash Code Table, page 94):– Breakage: 3 x flashes– Obstruction: 2 x flashesThe corresponding flash code is repeated every two seconds.

NOTICE! For the FAS-420-TP2 and FAS-420-TT2, the preparation for the function test (see above) and the following functional test (steps 1–7) are to be carried out for both detector modules and/or both pipe systems.



6.6.2 Conducting the Functional TestThe functional test can be conducted with or without a digital pressure gauge. The complete test is described below. If the test on the FAS-420 reveals deviations from the described procedure, the unit or its airflow sensor is defective.1. Make sure that the aspirating smoke detector has been operating for at least 30 minutes.2. Close all the test pipe’s aspiration borings with some duct tape.After a few seconds,

the LED flash code on detector module I and detector module II must signal an obstruction (see NOTE). After a short run-up time, the negative pressure must lie within the following range:– Fan voltage 6.9 V: 250 Pa to 310 Pa– Fan voltage 9 V: 460 Pa to 530 Pa.

3. Open all of the test pipe's aspiration borings. After a few seconds, the flash code of the LED must go out.

4. Remove the test pipe. The LED flash code on detector module I and detector module II must signal a breakage.

5. Reconnect the test pipe to the device. After a few seconds, the flash code of the LED must go out.

DIAG diagnostic softwareThe DIAG Diagnostic Software can be used to track airflow values during the function test. Save all diagnostics data as a file. To be able to compare the data read out, save each file under a different file name.Information for installing the diagnostic software can be found in Section 6.1 Preparation, page 85.

3. The fans are faulty or obstructed– If the fan connection is correct (troubleshooting step 2), the malfunction will

reoccur.– Measure the fan voltage (DC) using a multimeter.– If the fan voltage is outside the limits specified below, the fan may be faulty:

If the fan voltage is set at 6.9 V, the maximum permissible setting is 7.6 V and the minimum is 6.0 V.

If the fan voltage is set at 9.0 V, the maximum permissible setting is 10.0 V and the minimum is 7.8 V.

Replace the entire housing, as the fans cannot be removed.


7.2.4 4 Flashes - Error: Air Pressure Correction Voltage MonitoringIn operation with two detector modules, both LEDs flash. When troubleshooting, the following steps should be carried out in the specified order.1. The R3 potentiometer is moved to the setting for the pressure-dependent airflow

calibration.– Using a multimeter, measure the voltage (DC) at measuring points MP2 (x) and MP3

(-).– The default measurement value is 1.2 V. However, deviations may occur due to the

calibration of the airflow dependent on air pressure.– The measurement value must be between 0.5 V and 1.9 V. If the measured voltage

value is outside of this range, the R3 potentiometer setting is faulty.Note: The malfunction only occurs at voltages below 0.2 V or above 2.3 V.

7.4 Pipe systemCheck the pipe system and the air sampling openings for obstruction in areas susceptible to dust particles or icing. Where necessary, blow out the pipe system and air sampling openings using blast air (class 3 for recycling areas or class 2 for deep-freeze areas). Use a mobile cylinder of compressed air (blowing-out system) or activate the manual blowing-out system located on site. The components (compressors, compressed air containers, dryers) required to supply the compressed air can be obtained directly from the relevant compressed air system suppliers.

Blowing outThe compressed air supply to the pipe system must be connected so that only the pipe system itself is blown out. The aspirating smoke detector and the downstream accessory components of the pipe system (e.g. air filter) must not and cannot be blown out.A check valve must be installed at the end of each pipe branch. The check valve prevents damage to the air sampling openings and prevents dirt deposits from being blown through the pipe system. To prevent aspiration reducing film sheets in deep-freeze areas from tearing, it is advisable to use special deep-freeze aspiration reductions.The compressed air supply and compressed air connection must be installed so that at least 0.7 bar of pressure remains available per pipe branch within the pipe system. This means a minimum of 0.7 bar for the I-pipe, a minimum of 1.4 bar for the U-pipe and a minimum of 2.8 bar for the double U-pipe. The minimum flow cross-section within the compressed air connection must be taken into consideration. If the connection is made, e.g. via a quick release coupler with a flow cross-section of 7.2 mm, an approx. pressure ratio of 1:9 occurs due to the comparatively large flow cross-section within the pipe system (21.4 mm). If, for example, 8 bar of pressure is available at the quick release coupler, this would drop to approx. 0.9 bar due to the larger flow cross-section in the pipe system. In this case, the pressure would still be sufficient for an I-pipe system, but inadequate for U and double U-pipe systems.In plants where contamination of the pipe system/air sampling openings can be expected, the compressed air supply can be connected via a three-way tap. In plants exposed to heavy contamination (e.g. recycling plants) an automatic blowing-out system is recommended.For areas exposed to moderate contamination, in which blowing out is required only at prolonged intervals, the use of a mobile blowing-out system including refillable compressed air cylinder is recommended.

7.5 Check the airflow sensor calibrationCheck the airflow sensor value with the Diagnostic Software.Functional principleDuring initialization of the connected pipe system, the device saves the measured actual value of the airflow as a target value via the integrated airflow monitoring. This target value then serves as a reference value for the additional evaluation of any airflow malfunctions.

NOTICE! A hardware defect in the detector module is indicated by a permanently-lit detector module LED.

CAUTION! Before blowing out the pipe system, disconnect the FAS-420 from the pipe system; otherwise, the airflow sensor will be damaged.



Depending on the airflow threshold selected (see "Adapting the airflow sensitivity" in Section 3.3 Airflow Monitoring, page 36), the current airflow value during operation can fluctuate around this target value without triggering an airflow malfunction. Only if the selected airflow threshold is exceeded will the airflow malfunction be reported by the device and thus transmitted.Checking the current valueThe tolerance range of the selected airflow threshold and the actual and target values are represented in the diagnostic software. The boundaries (maximum/minimum) always correspond to a deviation of ±100 % from the saved target value. Check the deviation of the actual value from the target value. If there is a deviation of > ±70 %, you should make a prophylactic check of the pipe system (see section below on "Troubleshooting airflow malfunction").

Dependent on air pressureTo ensure long-term malfunction-free operation of the device, the airflow sensor must be calibrated according to the air pressure. Only with this type of calibration do low air pressure fluctuations remain within the monitoring window and thus in the permissible tolerance range. Independent of air pressureIf the sensor calibration is carried out independently of air pressure, fluctuations in the air pressure can cause undesired airflow malfunctions. The calibration of the airflow sensor may only be carried out this way if you ensure that no fluctuations in air pressure will occur in the immediate environment.

Troubleshooting airflow malfunctionIf the airflow calibration has been executed depending on air pressure and the actual value still does not lie within the tolerance range of the selected airflow threshold (airflow malfunction displayed on the device), then a type of disturbance value other than air pressure or temperature fluctuation exists.

1. In this case, check the pipe system for leaks and obstructions (see Section 6.5 Checking Airflow Monitoring, page 90, "Troubleshooting").

2. If this check reveals no malfunctions, check the airflow monitoring by connecting the test pipe and conducting the functional test in accordance with Section 6.6.2 Conducting the Functional Test.

3. If, during troubleshooting, the pipe network has been changed, the original configuration of the pipe network must be restored after the troubleshooting has been completed and the airflow must be recalibrated.

NOTICE! When the fire panel is in revision mode, the LOGIC·SENS is temporarily deactivated, allowing the detector modules to be checked quickly and directly.

CAUTION! If air pressure fluctuations are anticipated in the immediate environment, the airflow sensor must be calibrated dependent on air pressure (see also Section 3.3 Airflow Monitoring, page 36).

CAUTION! In case of a defect in the airflow monitoring, only authorized personnel may replace the detector module!


Maintenance | en 97


1. Observe the current airflow value during ongoing maintenance or check it at the latest during the next inspection.

2. If the target value is similar to the previous one, disruptive environmental influences are the cause of the deviation. If these negative influences on the airflow monitoring cannot be suppressed, the next less-sensitive threshold should be set.

7.6 Airflow monitoringA pipe break or pipe obstruction is indicated for each detector module via the flash code of an LED on the motherboard. Check the airflow monitoring in accordance with Section 6.5 Checking Airflow Monitoring, page 90.

7.7 Malfunction TransmissionA malfunction is indicated on the FAS-420 and on the fire panel, where applicable. Proceed in accordance with Section 6.4 Checking Malfunction Transmission, page 90.

7.8 Maintenance IntervalsMaintenance comprises regular inspections and maintenance routines. The smoke aspiration systems should be checked when commissioned and then quarterly. At each fourth check, more comprehensive checks should be made, as described below:– Quarterly test/inspection– Annual test/maintenance + 4th annual inspection

Maintenance and 4th annual inspection

NOTICE! It is essential that you adhere to the calibration type (air-pressure-dependent or air pressure-independent) and, if necessary, the values for air pressure, height above sea level, and set voltage on MP1/MP4 in the test log.

NOTICE! The diagnostic software can be used to save all stored and current diagnostics data, as well as the settings made via the RPS programming software as a file. To be able to compare the data read out, save each file under a different file name.
